For a midnight snack eaten by one person, start with a multipack that states the weight of each sealed bag, rather than choosing by bag count alone. A mixed case makes more sense if you will use its assortment, while a box of sharing bags suits snacks that will actually be shared or portioned out. Check the current label for the weight, salt and ingredients of every flavour you plan to eat.
A sealed individual bag gives you a stated amount without leaving a sharing bag open. Check its weight: Which? reported in 2023 that Walkers Ready Salted came in a 25g multipack bag and a 45g grab bag, both presented as individual portions.
Check how many bags of each flavour the case contains and whether they will be used by the best-before date. REAL Crisps lists a mixed case of 24 × 35g bags; Kettle Chips’ Originals Box instead contains eight 130g sharing bags.
Read the label for each flavour, not just the brand name or outer-pack description. For example, Walkers lists milk ingredients in Lightly Cheese & Onion, while salt figures and dietary-suitability statements on other brands’ pages apply to their named products.
Choose the bag format for the occasion first, then compare the exact weights, flavours and labels within that format.
Choose when: One sealed bag is the amount you intend to open for a solo snack.
Bear in mind: Bag count does not tell you how much is in each bag.
Choose when: Several snackers, or repeated snacks, will use the included flavours.
Bear in mind: A larger case commits you to its bag sizes and flavour selection.
Choose when: The bag will be shared or you plan to put a chosen amount into a bowl.
Bear in mind: A sharing bag is not equivalent to one small, sealed snack bag.
| Priority | What to check | Your needs |
|---|---|---|
| Bag format | Compare grams per bag and total net weight. Check whether the bags are individual or sharing sizes; a stated serving may be smaller than a sharing bag. | I want to open one bag for a midnight snack, so its actual weight matters more to me than the number of bags in the outer pack. |
| Salt and nutrition | Read the current nutrition panel for the exact flavour, using the per-bag figure alongside per 100g where shown. Check what product a reduced-salt or reduced-fat claim compares with. | If I eat crisps regularly, I want to know what is in the bag I will actually open, rather than rely on a claim about the brand or product line. |
| Ingredients | Check ingredients, highlighted allergens and dietary statements for every included flavour. Do not extend one flavour’s statement to a mixed pack. | A familiar brand name is not enough if I need to avoid an ingredient or choose a particular type of product. |
| Flavour assortment | Check the flavour breakdown, number of bags and best-before date. For a mixed case, confirm that its bag size suits the intended snack. | I would choose a larger assortment only if the people eating it are likely to use the included flavours in time. |
More bags need not mean more crisps or a bag size that suits your snack. Which? reported in 2023 that Walkers Ready Salted’s 25g multipack bag and 45g grab bag were both presented as individual portions.
Compare total net weight and grams per bag before deciding which format to buy.
Kettle Chips lists eight 130g sharing bags in its Originals Box, while REAL Crisps lists 35g individual bags in its mixed case. Opening one bag therefore means something different in each format.
For a solo snack, choose an individual bag or put your intended amount from a sharing bag into a bowl.
Ingredients and dietary suitability can differ between flavours. Walkers Lightly Cheese & Onion contains milk ingredients, and Kettle Chips’ Originals Box includes a Mature Cheddar & Red Onion flavour with milk ingredients.
Check the current ingredient, allergen and nutrition information for each flavour in the exact multipack.
These examples show why the named flavour and pack format matter; they do not establish what is in every product from a brand.
Its standard, Oven Baked and Lightly lines give shoppers different named products to compare.
Lightly Sea Salted is an example for comparing an individual bag with larger sharing formats.
The KETTLE Originals Box is a selection of sharing bags rather than a small-bag multipack.
Its named crinkle-cut flavours offer another bag size and label to compare.
Pipers describes its range in terms of bold flavours; the exact seasoning remains a product-level choice.
REAL offers a mixed case of individual bags for repeated snacks or a household assortment.
These multipacks offer individual bags for solo snacks or stocking up. They include variety and single-flavour options; check each listing’s current flavours, bag weights and labels before choosing.

This variety multipack contains twelve 24g bags. Hula Hoops are a shaped potato-based snack rather than sliced potato crisps, so check the product type and each flavour’s ingredients if either distinction matters to you.
Check the grams in each bag, not just the outer pack’s bag count. For comparison, REAL Crisps lists 35g individual bags in its mixed case, while Kettle Chips lists 130g sharing bags in its Originals Box. Use the actual bag weight and nutrition panel to decide how much you intend to open.
No: compare the exact products and their current nutrition panels as well as the bag sizes. Walkers states that Oven Baked Sea Salt has 50% less fat than regular potato crisps and that Lightly Cheese & Onion has 45% less salt than the average salt value of regular potato crisps. Neither statement describes every flavour or multipack.
Read the current ingredient and allergen information for every flavour in the pack. Walkers Lightly Cheese & Onion contains milk ingredients, for example, while dietary-suitability statements from Seabrook and Pipers concern their named products. Do not assume that all flavours in a mixed case have the same recipe.
Compare the salt stated for the amount you would eat, and use per 100g figures when comparing products with different bag weights. Walkers lists 0.16g salt per 25g pack for Lightly Cheese & Onion; Seabrook lists 0.4g per 31.8g bag for Beefy. Those are figures for different named products, so check the current label of the multipack you choose.
